Definitions

  • the present invention relates to a wrench and, in particular, to an adjustable wrench that includes a reinforcing device for increasing its structural strength to prevent the deformation of two walls of a rail of the adjustable wrench caused by improper operation or impinged by an outside force.
  • a conventional wrench is a tool used to provide grip and mechanical advantage in applying torque to turn objects, usually rotary fasteners, such as nuts and bolts, or keep them from turning.
  • One type of the wrench is called open end wrench, which has a U-shaped opening to grip two opposite faces of the bolt or nut.
  • This wrench is often double ended, with a different-sized opening at each end. The ends are generally oriented at an angle of around 15 degrees to the longitudinal axis of the handle. This allows a greater range of movement in enclosed spaces by flipping the wrench over.
  • an adjustable wrench is a wrench with a jaw of adjustable width, allowing it to be used with different sizes of fastener head rather than just one fastener, as with a conventional open end wrench.
  • U.S. Patent No. 8,136,429 discloses an adjustable wrench, which includes a handle, a head, a slidable jaw, an axial rod and a worm gear.
  • the head is formed with a fixed jaw, a sliding rail, and a receiving slot.
  • the slidable jaw has a sliding rod slidably disposed in the sliding rail of the head.
  • the axial rod and the worm gear dispose in the receiving slot of the head, and the worm gear engages with the sliding rod of the slidable jaw to control the movement of the slidable jaw in relation to the fixed jaw so that an opening formed between the fixed and slidable jaw can be adjustable for different sizes of fastener head.
  • the sliding rod will push against the sliding rail to cause the deformation of two walls of the sliding rail.
  • the present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
  • an adjustable wrench includes a handle, a head, a slidable jaw, an adjusting assembly, and a reinforcing device.
  • the head is formed at one end of the handle and includes a fixed jaw, a sliding rail, a receiving slot, two lateral walls, and two connecting portions.
  • the fixed jaw is formed at one end of the two lateral walls.
  • the sliding rail is formed between the two lateral walls.
  • the receiving slot is connected and in communication with the sliding rail.
  • Each connecting portion is formed one end of each lateral wall opposite to the fixed jaw.
  • the slidable jaw is slidably disposed in the sliding rail of the head.
  • the adjusting assembly is positioned in the receiving slot of the head and includes an axial rod and a worm gear.
  • the axial rod inserts through the worm gear, and the worm gear is engaged with the slidable jaw.
  • the reinforcing device connects the two lateral walls and is engaged into the two connecting portions.
  • an advantage of the adjustable wrench according to the present invention is that the adjustable wrench includes a reinforcing device for increasing its structural strength to prevent the deformation of two lateral walls of a sliding rail of the adjustable wrench caused by improper operation or impinged by an outside force.
  • FIGS 1 through 4 show an adjustable wrench in accordance with a first embodiment of the present invention.
  • the adjustable wrench includes a handle 10, a head 20, a slidable jaw 30, an adjusting assembly 40, and a reinforcing device 50.
  • the handle 10 is adapted for gripped by a user.
  • the head 20 is formed at one terminal end of the handle 10. Moreover, another end of the handle 10 may also be provided with another head 20.
  • the head 20 includes a fixed jaw 21, a sliding rail 22, a receiving slot 23, two lateral walls 24, and two connecting portions 25.
  • the fixed jaw 21 is formed at one end of the two lateral walls 24.
  • the sliding rail 22 and the receiving slot 23 are connected and in communication with each other.
  • the sliding rail 22 is formed between the two lateral walls 24.
  • each of the two connecting portions 25 is a through hole formed on an end face 241 of each lateral wall 24 opposite to the fixed jaw 21 and extending toward the fixed jaw 21.
  • the slidable jaw 30 is slidably disposed in the sliding rail 22 of the head 20.
  • the adjusting assembly 40 is positioned in the receiving slot 23 of the head 20 and includes an axial rod 41 and a worm gear 42.
  • the axial rod 41 inserts through the worm gear 42 so that the worm gear 42 is moveable and rotatable in relation to the axial rod 41.
  • the worm gear 42 is engaged with the slidable jaw 30 to control the movement of the slidable jaw 30.
  • the reinforcing device 50 connects the two lateral walls 24 and is engaged into the two connecting portions 25.
  • the reinforcing device 50 is a U-shaped one-piece structure.
  • the reinforcing device 50 is formed with a body section 51 and two leg sections 52 extending from two opposite ends of the body section 51. An extending direction of each leg section 52 is substantially perpendicular to that of the body section 51.
  • the two leg sections 52 are securely engaged into the two connecting portions 25 of the head 20, and the body section 51 is abutted against the end face 241 of each lateral wall 24.
  • the body section 51 of the reinforcing device 50 connects the two lateral walls 24 increase the structural strength to prevent the deformation of two lateral walls 24 caused by the slidable jaw 30 pushing against the sliding rail 22.
  • the slidable jaw 30 is provided with a sliding rod 31 and a contact portion 32 slidably disposed in the sliding rail 22 of the head 20.
  • the sliding rod 31 is engaged with the worm gear 42 so that the user can rotate the worm gear 42 to control the movement of the slidable jaw 30 in relation to the fixed jaw 21 to adjust the width of the opening to be used with different sizes of the object.
  • the contact portion 32 has a curved contact surface 321 disposed opposite to the fixed jaw 21 and contactable with the body section 51 of the reinforcing device 50 to provide the maximum width of the opening.
  • the head 20 further includes a lateral through hole 26 connected and in communication with the receiving slot 23.
  • One end of the axial rod 41 inserts through the worm gear 42, and another end of the axial rod 41 is threadly engaged into the through hole 26.
  • the adjusting assembly 40 further includes an elastic member 43, which may be a coil spring mounted around the axial rod 41 and elastically abutting against an inner surface 231 of the receiving slot 23 and a lateral end face of the worm gear 42.
  • FIGS. 5 and 6 show an adjustable wrench in accordance with a second embodiment of the present invention.
  • the structure of the adjustable wrench of the second embodiment is substantially similar to that of the first embodiment except that the reinforcing device 50a includes a connecting member 51a, two connecting holes 52a formed at the connecting member 51a and corresponding to the two connecting portions 25 of the head 20, and two fastener members 53a inserting through the two connecting holes 52a and engaging into the two connecting portions 25 of the head 20.
  • the connecting member 51a is abutted against the end face 241 of each lateral wall 24 and contactable with the curved contact surface 321.
  • FIGS. 7 and 8 show an adjustable wrench in accordance with a third embodiment of the present invention.
  • the structure of the adjustable wrench of the second embodiment is substantially similar to that of the first embodiment except that each of the two connecting portions 25a is a slot formed on a lateral face 242 of each lateral wall 24 and extending toward the fixed jaw 21.
  • An extending direction of the lateral face 242 of each lateral wall 24 is substantially perpendicular to that of the end face 241 of each lateral wall 24.
  • the two leg sections 52 are securely engaged into the two connecting portions 25a of the head 20
  • an object of the present invention to provide an adjustable wrench that includes a reinforcing device for increasing its structural strength to prevent the deformation of two lateral walls of a sliding rail of the adjustable wrench caused by improper operation or impinged by an outside force.
